Controlling the activity of peptides and proteins with smart nucleic acid-protein hybrids.
Oligonucleotide-peptide conjugates have frequently been used to control the localisation of the conjugate molecule. For example, the oligonucleotide segment has allowed spatially addressed immobilization of peptides and proteins on DNA-arrays via hybridisation while the peptide part has most frequently been used to confer transfer of oligonucleotide cargo into live cells. The regulation of functional properties such as the affinity of these bioconjugates for protein targets has rarely been addressed. This review article describes the current developments in the application of smart oligonucleotide-peptide hybrids. The mutual recognition between nucleic acid segments is used to constrain the structure or control the distance between peptide and protein segments. Application of these new type of oligonucleotide-peptide hybrids allowed not only the regulation of binding affinity of peptide ligands but also control of enzymatic and optical activity of proteins.
